Looking through old issues of the Incredible Hulk, I notice many of the issues he is gray, and many he is green, why the difference?

Because Stan Lee wanted a scary, non-used color. He switched to green because Stan decided a different, not-so-boring color. In the comics Hulk is dosed with extra radiation, which made him change colors. Jan 22 06, 2:19 PM

It appears that "The Hulk" was originally grey, but technical difficulties made it difficult to maintain a consistent shade of grey so they changed him to green instead. In 1986, when things had advanced a little, they changed him back to his intended grey but fans were now used to the green so he was changed again in 1991.
